Features
Leonova Emerald IS includes the High Definition Shock Pulse Method (SPM HD®) for bearing condition and advanced vibration analysis for general machine condition and more features, see below.
The SPM HD® Method (HDm/HDc)
The SPM HD® method is a patented further development of the Shock Pulse Method (SPM) in being less sensitive to interference from other signals and therefore unique in its ability to measure from very low rpm (0.1 - 20.000 RPM range). SPM HD is used for fast, easy, and reliable diagnosis of the operation condition of rolling element bearings.
SPM Spectrum™
SPM Spectrum™ is based on extraordinary signal quality and 24 bit A/D conversion that provides razor-sharp resolution and helps determine where a possible bearing damage is located with very high precision.
LR/HR
The LR/HR method was developed from the original Shock Pulse Method for condition diagnosis of rolling element bearings and allows a precision analysis of oil film condition in the rolling interface.
dBm/dBc
The original Shock Pulse Method is based on dBm/dBc that counts the rate of incoming shock pulses per second and provides one value for the shock carpet level and one value for the maximum level (peaks).
VIBRATION ANALYSIS
The HD ENV® technique
HD ENV® is a patented enveloping technique used for early detection of impact-related events such as gear and bearing damage. A number of predefined filters are available for easy selection; each designed to detect damages in different failure stages. The method utilizes cleverly engineered algorithms for digital signal processing to obtain optimal data for trending purposes.
Vibration Severity plus FFT Spectrum
Measurement of vibration velocity, acceleration and displacement (0-20kHz frequency range) according to the latest ISO 10816 standards helps to diagnose general machine condition. In addition to the RMS vibration readings, the instrument displays an FFT spectrum, where symptoms of imbalance, misalignment, and structural weakness are easily identified.
EVAM
The EVAM (Evaluated Vibration Analysis Method) measuring technique produces up to 12800 line spectrum with true zoom, provides ready-made machine 'fault symptoms' as well as trending.
CORRECTIVE MAINTENANCE
Dynamic balancing
Field rotor balancing in single plane according to ISO 1940-1 standard with an initial vibration measurement guiding the user through a balancing procedure with suggestions for correcting the imbalance.
ORDER TRACKING
HD Order Tracking
On machinery operating under variable speed, analysis with HD Order Tracking provides reliable data and crystal-clear measuring results even when RPM varies greatly during the course of measurement. Order tracking is applicable in a very wide RPM range, from just a few to thousands of revolutions per minute.
Technical Overview
Leonova Emerald IS is lightweight, ergonomic, and easy to operate. Load measuring rounds to Leonova from the PC, then simply measure and save. All input data is pre-programmed. You get an instant condition evaluation on a green-yellow-red scale.
The instrument will deliver long working life under the toughest, most demanding circumstances. Leonova Emerald IS comply with the strictest ATEX/IECEx standards and thus can be used in zones 0 - 2.
